Default video alignment:
Default stretch mode
None: do not stretch the video at all. This is the default option, for men of culture.
Basic: stretches video to fit the player or screen unconditionally. If video has letterbox encoded, this option will not try to remove letterbox before stretching. You probably shouldn't be using this option.
Hybrid: stretches the video to fit the player, but only if cropping didn't completely remove the black bars.
Thin borders: stretches only if the width of black borders after cropping is thin.
Treshold for thin borders can be defined below.

## Advanced automatic detection options

Aspect ratio check frequency

Options here decide how often the extension will check for changes in aspect ratio of a given video.

Values are given in milliseconds. Longer intervals increase delay between aspect ratio changing and extension re-correcting for the change. Using shorter intervals than the default ones can cause lage and immense RAM usage.

Check frequency when video is playing (ms):
Check frequency when video is paused (ms):
Recheck delay on error (ms):
Fallback mode

In order for autodetection to work, the extension grabs a frame of the video you're watching and takes a look at it. Some websites use DRM, which prevents you from using the HTML5-blessed way of getting a frame from a video. Some browsers offer some features that can be used to circumvent DRM protection. With this option enabled, the extension will use said features to basically do that.

At the moment, Firefox is the only browser to support this.

This browser doesn't support fallback mode.

## Ultrawidify - an aspect ratio fixer for youtube (and netflix)

Created by Tamius Han (me). If something is broken, you can shout at me on github (shout nicely, though. Open an issue or bug report or something). If you're curious to see the source code, github's here. If you're looking at this page because you're bored and want to be bored some more, my website's here.

## So you want to help?

Alan pls add quick description.
